[0002] Gantry crane is a type of bridge crane with a horizontal bridge frame set on two legs to form a portal shape; this type of crane runs on ground tracks and is mainly used for handling and installation operations in open storage yards, docks, power stations, ports and railway freight stations. The lifting mechanism, trolley running mechanism and bridge structure of the gantry crane are basically the same as those of the bridge crane; the lifting trolley of the gantry crane runs on the bridge frame, and some lifting trolleys are a boom crane.

[0003] However, traditional gantry cranes cannot carry other mechanical equipment to perform diversified work, which reduces the utilization rate. For example, the prior art patent with authorization announcement number CN206827943U discloses a gantry crane with the function of diving vertical cutting objects, including a gantry crane body, vertical brackets are provided at both ends of the gantry crane body, a crossbeam boom is mounted on the upper end of the vertical bracket, and lifting and lowering cutting machine devices are installed at both ends of the bottom of the crossbeam boom, and a cutting support is provided at the lower end of the lifting and lowering cutting machine device.

In the above manner, the utility model can be used as a gantry crane to perform high-power lifting work, and the gantry crane body is also equipped with a lifting and lowering cutting machine device to perform cutting work.

[0004] Although the above-mentioned technologies can realize the lifting of goods and the cutting of objects, both are operated independently and have not been effectively combined, so that the diversified work of the gantry crane carrying other mechanical equipment has not met the convenience requirements. Summary of the invention

[0014] Preferably, the traveling driving mechanism includes a horizontal chute, a load-bearing traveling seat, a transverse lead screw, and a first servo motor. A horizontal chute is provided on the horizontal bridge, and a transverse lead screw is rotatably installed in the horizontal chute. The first servo motor is fixedly installed on the horizontal bridge, and the transverse lead screw is fixedly connected to the output end of the first servo motor. Both of the two load-bearing traveling seats are threadedly installed on the transverse lead screw, and the load-bearing traveling seat slidably penetrates and is connected in the horizontal chute. The lower end of the load-bearing traveling seat is fixedly connected to the upper end of the electric hoist trolley. The moving directions of the two load-bearing traveling seats are the same.

[0015] Preferably, the object cutting mechanism includes a counterweight, a motor base, a cutting motor, a cutter and a protective cover. The lower end of the counterweight is fixedly connected to the motor base. The cutting motor is fixedly installed on the motor base, and the output end of the cutting motor is fixedly connected to the cutter. The protective cover is fixedly connected to the motor base. The cutter movably penetrates through the inner cavity of the protective cover, and the lower part of the cutter is located outside the protective cover. The counterweight is movably installed on the main gantry through a lifting and diving mechanism.

[0016] Preferably, the lifting and diving mechanism includes a Z-axis slide rail and a lifting sleeve. Z-axis slide rails are fixedly installed on both sides of the main gantry. The lifting sleeve is slidably installed on the Z-axis slide rail. The counterweight is fixedly connected to the lifting sleeve.

[0019] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0020] (1). In this application, the goods are fixed on the hook assembly. During work, the second servo motor works to drive the first bevel gear to rotate, that is, the two second bevel gears rotate accordingly, so that the two worm gears rotate, and the rotation directions are opposite. Then, the two worm wheels are driven to rotate, so that the two winding shafts rotate, and the rotation directions are opposite. The two cable reels respectively wind or release the two wire ropes, thereby realizing the traction lifting of the goods for transporting materials. The operation is simple and the stability is high.

[0021] (2) In this application, when the first servo motor operates, it will drive the horizontal lead screw to rotate, enabling the load-bearing walking seat to move along the horizontal chute. The track walking wheels will then roll along the rail groove, making the movement of the load-bearing walking seat smoother and more stable, ensuring the stability of the electric hoist trolley. The load-bearing walking seat can then slowly move the electric hoist trolley to carry goods. Moreover, the load-bearing walking seat is mainly supported by the horizontal bridge to reduce the wear of the horizontal lead screw and extend its service life.

[0022] (3) In this application, an object cutting mechanism is assembled, enabling the gantry crane to have the function of cutting objects. The movement of the object cutting mechanism is closely related to the movement of the electric hoist trolley. When the electric hoist trolley moves to the left, it will pull the object cutting mechanism on the right side to rise, while the object cutting mechanism on the left side will move downward under the traction of its own gravity. The lifting sleeve slides along the Z-axis slide rail, causing the counterweight to drive the cutting motor downward. Place the object to be cut on the object cutting table on the left side. When the cutting motor operates and drives the cutting tool to rotate, the cutting tool on the left side will rotate and move downward to complete the diving vertical cutting of the object, combining the moving cutting action with the goods handling action, greatly reducing the on-site operation intensity.

The operation is simple and the stability is high;

[0052] The first servo motor 204 operates, which will drive the horizontal lead screw 203 to rotate, enabling the load-bearing walking seat 202 to move along the horizontal chute 201, and the track walking wheels 2023 to roll along the track groove 206, making the movement of the load-bearing walking seat 202 smoother and more stable, providing guarantee for the stability of the electric hoist trolley 3.

The load-bearing walking seat 202 is mainly supported by the horizontal bridge 2 to reduce the wear of the horizontal lead screw 203 and extend its service life;

[0053] An object cutting mechanism is assembled, enabling the gantry crane to have the function of cutting objects. The movement of the object cutting mechanism is closely related to the movement of the electric hoist trolley 3. For example, when the electric hoist trolley 3 moves to the left, it will pull the object cutting mechanism on the right side to rise, while the object cutting mechanism on the left side will move downward under the traction of its own gravity. The lifting sleeve 102 slides along the Z-axis slide rail 101, causing the counterweight 103 to drive the cutting motor 105 to move downward. Place the object to be cut on the object cutting table 5 on the left side. The cutting motor 105 operates and drives the cutter 106 to rotate. Thus, the cutter 106 on the left side rotates and moves downward to complete the diving vertical cutting of the object; Similarly, when the electric hoist trolley 3 moves to the right, the cutter 106 on the right side completes the cutting task, combining the moving cutting action with the goods handling action, greatly reducing the on-site operation intensity.
